When logic gates are combined, they form . These are divided into two main categories:
| Gate | Symbol | Boolean Expression | Truth Table (A,B → Output) | |------|--------|--------------------|----------------------------| | AND | • | A · B | 00→0, 01→0, 10→0, 11→1 | | OR | + | A + B | 00→0, 01→1, 10→1, 11→1 | | NOT | ¬ | Ā | 0→1, 1→0 | | NAND | ↑ | ¬(A·B) | 00→1, 01→1, 10→1, 11→0 | | NOR | ↓ | ¬(A+B) | 00→1, 01→0, 10→0, 11→0 | | XOR | ⊕ | A·¬B + ¬A·B | 00→0, 01→1, 10→1, 11→0 | When logic gates are combined, they form
Every time you click a mouse, stream a video, or compile a line of code, you are standing on the shoulders of a four-decade-old technological marvel. But how many people understand the chain of abstractions that transforms a physical piece of sand into a logical thought? In a , you would see the classic
In a , you would see the classic MIPS or RISC-V datapath with all control signals labeled: RegWrite, ALUSrc, MemRead, MemWrite, etc. When logic gates are combined
For those seeking on these topics, it is essential to reference academic and industry standards:
